Maxillary cyst: description of a clinical case.

Aim Of The Work: Aim of this work is to evaluate the efficacy of the Partsch I surgical technique which is considered to be first choice in the treatment of cystic lesions according to the international literature and also to evaluate the regeneration capacity of the bone tissue without any grafting procedure.

Materials And Methods: The patient reported pain in the second quadrant. The objective intraoral examination showed a swelling which was of a hard-elastic consistency and, the x-ray, opt and ct scan exams showed an osteolitic lesion which expanded from the element 2.3 to the elment 2.6 involving the maxillary sinus, too. The lesion was removed by the Partsch I method after disinfecting and shaping the radicular canals of the 2.3 element. It was assessed that the maxillary sinus requested no treatment for the presence of a thin cortical layer residue. The removed neoformation was then sent to the Anatomy and Histology Pathology Service.

Results: The histologic test confirmed the radicular origin of the odontogenic neoformation containing a necrotic-hemorrhage. Clinically the post-operative course showed no complications, with a good healing of the bone tissue and there was no oral-antral communications.

Conclusions: The clinical results obtained confirmed the validity of the enucleation technique in the treatment of cystic neoformations. Such approach has always to be preferred because it presents no intraoperative risks, especially for what it concerns the post-operative course. It has also been confirmed the great capacity for the bone tissue to regenerate following the organization of the hematic coagulum.
